Abstract: Dilaton effective field theory (dEFT) can be employed to analyze lattice data in gauge theories thatlie in close proximity of the lower edge of the conformal window. Under special conditions, we showthat it can be used as a diagnostic tool to distinguish near-conformal, yet confining, theories frominfrared conformal ones. We demonstrate this efficacy by analyzing two sets of lattice measurementstaken from the literature. For the SU(3) theory coupled to Nf = 8 Dirac fermions transforming inthe fundamental representation, our analysis favors confinement. For the SU(2) theory with Nf = 1adjoint fermion, our fits favor infrared conformal behavior. We discuss future lattice measurements,and analysis refinements, that can further test this framework.
